Design quality, massive features & flexibility, extremely easy to customize to build ANY user experience, good documentation, code quality is VERY clean.
SUPPORT in my experience in dealing with dozens of dopey slow dev support people that do not read the question or are smart a$$ is 2nd to none. We have multiple purchases & deployments & have done some crazy configs...the COMPOSER team is the real deal. Relwan & company are relentless at solving issues, suggestions, code modifications & CSS changes. They have NEVER let us down with either logging in & digging in and changing or sending the CSS or CODE mods for us to change.
We plan to continue to work with the COMPOSER team on upcoming projects. We look forward to seeing their continued success. MOST Themeforest themes are from dev orgs that produce average, most suck at supporting their own product.
I chose Other because, there was no option to select many reason, I am choosing 5Star. So, here are my reasons: Flexibility, Feature Availability, Design Quality, Customer Support and Customizability.
This is one of the Finest and Awesome theme I have ever use from themeforest. Most of the time, I rarely use the same theme for differ projects, because I know most multipurpose themes offer such, but don't just cut it for me. But, this theme defied the odds for me; with the feature rich availability of code blocks, you don't need much of the documentation to get going. Innwithemes have done a great and wonderful job with this Composer theme. With it, one can develop and finish projects within few days and very much look different from each other. And their support is quite responsive.
Overall a good multipurpose theme, the only thing that somehow kills it's functionality is the lack of a proper header builder (like in Themeco's Pro theme). Otherwise, a very solid theme with a multitude of options, easy to understand interface.
